Sport, my kids do not like it.

Might be the reason for it is a sport at school sucks or they simply like to use their brains more.

My kids have a high IQ and live in the other world.

They have a different way of thinking and because they are very creative, they survive and make something out of their lives.

It is normal for thinkers that their motions stay behind till a certain age or perhaps forever.

Both skills will seldom be developed at the same time on the same level. That is a reason why some kids can be extremely clumsy and others too stupid for words.

In most cases, it all will work out fine at a certain age.
The kid that was able to bicycle at the age of 2 years old does not seem to be braindead at all and the thinker can catch a ball, swim fast and bicycle too.

Schools, the place where teachers should be aware of this, do not care.
Everyone has to be the same, be at the same level. If not they give up on you.

My kids are lucky they have a very strong will.
They do not like to be a sheep in the cattle, they do not care about what others think or if they are liked (by kids or teachers). They are what they are.

My kids hate ballgames and running around by 30 degrees Celsius.
They do not see the benefit of getting hit by a ball, getting a heart attack while running aground while the fat teacher is chatting with the neighborhood.

No matter if it is about ballgames or gymnastics, sport at school is seldom about teaching, more a must.

You have to move a bit, being active for 40 minutes. No way you can improve yourself if you like it.
It is true many kids are too fat (not mine) but the sport will never be attractive if a teacher is not the shining example, is teaching something and let you pick up garbage left by others.

Kids with a high IQ can be interested in sport too if there is something to learn. If not they will teach you a lesson, sooner or later.
